A Home y June 6, 1933. R. c. HAYS TANK FILLER Filed April 1, 1931 2 Sheets-Sheet 2 /& 42 /4 A9 R 9 4 Inventor 4 ZdZ/J&,@fyy-i A Home y plug 16 is designed to be turned so as to communicate its angular air passage 17 with the air passage 14 or to close off the passage 14 as desired. Directly opposite the air passage 14 is an enlarged passage 18 communicating with the central aperture 15. In the passage 18 isdesigned to be screw-threaded a pipe 19"which has a handvalve 20, and

the pipe 19 is communicated with themani: fold or vacuum tank of theinternalcombustion engine. Projecting downwardly I and centrally of the cylinder 7 from a continua?v tion of the central bore or aperture is theiintak epipe is disposed directly above ,thepartition23 in thecylinderi a discharge .port 26.QThe spaceswithin the cylinder-1:7

below the partition 23 is rdesignated 27;"and it constitutes the float chamberi. oftthe" device iniswhich freely operates a float 28" of drum type which normally: rests upon and is confined within the-cylinder 7 by a pin 29 7 across the lower end of the cylinder '7: Just below the level of the partition% there-is formed a row of holes 30 communicating thi'ou ghtlie wall of the cylinder 7 into the =float chamber27-.

It will be observed that when the engine referredto' is] running, a vacuum or- :suction will be formed in thepip'e 19 which,-when the valve 20lis opened, wi-llbe communicated :to the passage 18.x Then, .whenithe: air passage '14 is closed by turning the plug 16, the

vacuum will be communicated through-the suction tube 21 to theinterior of the tank 5.; The pipe 24 having been connected with a liquid reservoir, the action; of the device under the-influence of'thejvacuul'n (described will be to draw vliquid'froniithezreservoir through said pipe 2 into the intake cham bei 1'25 and to i discharge it" into are tanki=5 throughthe-discharge port 26. As thevliquid within the tank 5 rises the floatl28-will 28 "closes the lower end of'the suction tube 21', andby closing communication ofthe v vacuum to the interior'of the tank 5'causes a cessation of inflow of; fluid into the tank The lower end of thesuction tube 21 is,

of cour se, placed at a f predetermined level.

This feature positively and automatically prevents over-flowing or over-filling of the tank 5, and consequently conserves "quantitles of fiui'dwh ch in other types of filling means for tanks ordinarily cause the tank three to overflow and waste, when the tank and the filling means are not constantly watched and attended. It will also be observed that no air being permitted to pass through the device during the filling operation, no extraneous substances such as dust and dirt can be'introduced into the tank-5 and. its contents, except through their presence in the fluid in the reservoir. Thus by properly strainin the fluid in the reservoirs the fluid may be introduced into the tank 5 in a perfect condition, without effort, and

" without additional expense, and the operationis carried oncompletely and safely and satisfactorily without attention from the operator of the internal combustion engine which operates the device. 1 It isto be definitely understood that I do *notjdesire ito limit the application of this inve'ntionxto the particular modification set out herein to illustrate the; principle there- .of;:and any "change or changes may be made in material and arrangement .andycombination of; parts consistent, with the spirit and scopeof the-invention.- 1 1 izWVhatwi s' c1aimed'.isi:-Y' .l-ZA' suction operatedfilling device for thez fuel tankof an; internal combustion enjgine comprising a vertical open ended cylindricalsca singidisposed to depend .within the 'tank, withnthe upperg portion thereof ex,- terior of 1 the tank,.: a partition mam-mediate the ends of the casingsand provided with a -.central; opening, a suction tube extending upwardly-fromthe, opening in the partition; ahead on theuupperfiendof-the casing, comprising a hollow body having a fuel intake 'means at'one sideya block in-its upper end provided in onesi-de 'witlra suctlon passage leading to the. upper end; of-said Tsuction tube, and ran 1 oppositely :located I relatively minute air intake passagerin saidrzblock h'aving communication with? said; suction I passageand .-suction.-:tube, 'and manual means ing'sa-id fblock cooperabler with the inward terminus (of. the air-intake passage; for closing and ;opening; communication thereof f with the suction? passage andsuctiontube, (said casing hav ng -a, fuel-entryport above; sa d; part1?- tion, and a freefloat:in-saidcasing below said partition, and adapted to rise and en.-
